The lamp control unit is used for analyzing and confirming that the working mode of the airport for forbidding to enter the light arranging mode is a first working mode or a second working mode according to the received control signal for controlling the airport for forbidding to enter the light arranging display state; when the first working mode is confirmed, the lamp control unit confirms that the airport is forbidden to enter a first target light level of the row lamps, and then outputs direct current voltage corresponding to the first target light level to the EMI protection circuit; the optical level detection circuit detects the output voltage of the EMI protection circuit and sends a detection result to the main control unit; the main control unit controls and outputs driving current corresponding to the first target light level to the airport to forbid entering into a light bank according to the detection result; when the second working mode is confirmed, the lamp control unit outputs preset constant direct-current voltage and a communication command; and the main control unit controls to output a driving current corresponding to a second target light level to the airport to forbid entering of the light bank, and lights or extinguishes the airport to forbid entering of the light bank according to the demodulation data of the communication command by the communication unit.

In specific operation, with reference to fig. 1, the communication unit includes a filter circuit and a modulation and demodulation unit, and the lamp control unit is connected to the main control unit through a shielding twisted-pair power line, the filter circuit and the modulation and demodulation unit which are connected in sequence; the modulation and demodulation unit is used for demodulating the communication command, and the main control unit controls and outputs driving current corresponding to a second target light level to the airport lamp bank forbidden to enter according to demodulation data, and lights or extinguishes the airport lamp bank forbidden to enter. The airport light-arranging forbidding control system further comprises an LED fault detection unit which is connected with the main control unit and the airport light-arranging forbidding, wherein the LED fault detection unit is used for monitoring the working state of the lamps in the airport light-arranging forbidding, and when the lamps are short-circuited or open-circuited, the LED fault detection unit informs the main control unit to close the output channel so as to protect the lamp driving unit.

Specifically, the light level at which the airport is prohibited from entering the row lamps may include five levels, where the lamp control unit outputs the dc voltage to a preset first voltage value (e.g., 9VDC, etc.) when the light level at which the airport is prohibited from entering the row lamps is the first level, outputs the dc voltage to a preset second voltage value (e.g., 10VDC, etc.) when the light level at which the airport is prohibited from entering the row lamps is the second level, outputs the dc voltage to a preset third voltage value (e.g., 12VDC, etc.) when the light level at which the airport is prohibited from entering the row lamps is the third level, outputs the dc voltage to a preset fourth voltage value (e.g., 13VDC, etc.) when the light level at which the airport is prohibited from entering the row lamps is the fourth level, and outputs the dc voltage to a preset fifth voltage value (e.g., 15VDC, etc.) when the light level at which the airport is prohibited from entering the row lamps is; the constant dc voltage is a preset sixth voltage value (e.g., 12VDC, etc.).

The lamp control unit realizes the control of lighting or extinguishing of the lamp by cutting off the connection relation between the shielding twisted-pair power line and the drive of the lamp prohibited from entering the bank light. The positive end of the shielding twisted-pair power line coupled with the modulated and demodulated communication command is connected to an EMI filter circuit connected to the lamp driver, the voltage amplitude is identified by the light level detection circuit and is output to the main control unit for judgment, and then the LED driver is driven to output the driving current corresponding to the light level.

The LED fault detection unit monitors the working state of the LED lamp beads, and when the LED lamp beads are short-circuited or open-circuited, the main control unit is informed to close the output channel so as to protect the driving circuit.

In the embodiment, the lamp control unit adopts a direct-current power supply mode, so that the engineering construction cost of the system deployment process and the input cost of system hardware facilities can be remarkably reduced, the regulation and control of the on-off and light level output of the lamp can be realized through a first working mode (namely a centralized power control mode) or a second working mode (namely a communication command mode), and the problem that the detection and control communication of the navigation aid lamp in the existing power carrier communication technology is unreliable is solved.
